September 16th, 2025

When it comes to serving hot or cold beverages quickly and efficiently, an airpot-style thermal flask is the go-to solution. The latest model RD-2045ST3.E made by Rang Dong, Vietnam’s leading manufacturer of vacuum flask products, stands out with its large capacity and user-friendly pump mechanism, which simplifies the beverage service. Built with a stainless steel body, high-performance glass liner and a push-button lid, the flask perfectly delivers both function and style. 

Rang Dong’s RD-2045ST3.E model is expertly designed for users who value both capacity and performance. Capable of storing 2 liters of either hot or cold drinks, the flask caters to personal and group use. 

The flask body is made of durable tinplate, adorned with modern horizontal stripe patterns that give it a sleek and premium appearance. A large, sturdy black handle allows for easy transport, making it suitable for both indoor and outdoor use.

Rang Dong’s flask features a PP plastic lid with a built-in push button that activates the internal pump mechanism, delivering water or drinks without the need for tilting.  

The spout includes a long suction pipe that reaches deep into the flask for a complete pouring. The inner glass refill is manufactured using advanced Japanese technology to provide excellent heat retention properties, as the flask can keep liquids hot for up to 12 hours, and cold for up to 24 hours. 

Exceptional features 

Rang Dong’s airpot-style thermal flask is packed with features designed to enhance ease of use and efficiency.  

Its standout function is the pump-style pouring mechanism, activated by a top push button, which eliminates the mess and effort typically associated with traditional flasks. Users can dispense drinks with just one hand, making it highly convenient in busy environments. 

 

Model RD-2045ST3.E is the ideal thermal container for modern users. 

The mouth of the flask is designed to deliver a smooth and even flow, minimizing spills and preventing overflow. A silicone gasket provides airtight sealing and superior leak protection. The flask’s PP plastic base is skid-resistant, and it can be easily disassembled for cleaning. 

Beyond its functional value, the overall design balances aesthetics with practicality, so the flask fits well in professional settings, from meeting rooms to office pantries.   

This product from Rang Dong meets high safety and environmental standards, backed by LFGB and SVHC certifications, Europe’s key standards for food contact safety and protection of human health and the environment against harmful chemicals. 

Applications 

This airpot-style thermal flask is the perfect solution for households, offices, conferences, and hospitality environments. Its large capacity and easy-pour functionality provide an ideal beverage service such as coffee, tea, water or herbal drinks throughout the day without frequent refills.   

Airpot-style thermal flasks are ubiquitous in coffee shops and restaurants for self-service coffee, hot water for tea, hot chocolate, or even iced tea.  

From a kitchen counter to a meeting room table, the flask keeps the beverages at the desired temperature for hours. The push-pump design is especially useful in environments where hygiene, speed and minimal handling are essential.  

This product also makes an excellent travel companion for outdoor events and family trips.  

Having already established a strong market presence in Middle Eastern countries such as Saudi Arabia, Kuwait and the UAE, Rang Dong’s airpot-style thermal flask meets a variety of cultural and practical demands.
